PETER. A. BURLOG, OF UPHAM, NORTH DAKOTA.

TOOL-HOLDER.

To all whom it may concern:

Be it known that I, PETER A. BURLOG, a citizen of the United States, residing at Upham, in the county of McHenry and State of North Dakota, have invented certain new and useful Improvements in Tool-Holders, of which the following is a specification, reference being had to the accompanying drawm s.

lhis invention relates to new and useful improvements in tool holders and more par ticularly to punch or chisel holders, the object of the invention being to provide a holder of the above character whereby a punch or chisel may be suitably suspended in an upright operative position, thus leaving both hands of the operator free to hold the material and the hammer or other tool which is to be used.

Another object of the invention is to pro vide a holder of the above character which will possess advantages in points of eflicienoy and durability, is inexpensive of manufacture and at the same time is simple in construction and operation.

With the above and other objects in view, this invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claim and shown in the accompanying drawings, in which- Figure 1 is a side elevation of a tool holder constructed in accordance with my invention; Fig. 2 is a top plan view of the outer end of the supporting arm; and Fig. 3 is a transverse sectional view through the standard looking down upon the operating lever.

Referring more particularly to the drawings, 1 indicates the supporting base in which is mounted the lower end of the upright standard 2. Arranged transversely within the upper end of the standard is a suit-able pin 3, upon which is pivotally mounted the supporting arm 4, said arm being provided upon its lower longitudinal edge with a plurality of notches 5 adapted for the reception of the pin 3 whereby the arm may be adjusted longitudinally, to various positions. A guide member 4 is arranged over the arm 4 at its pivot point, said guide comprising a plate having its intermediate portion bent to provide an offset 5 to engage over the arm and prevent longitudinal movement of the same upon the pin 3. i

Specification of Letters Patent.

Application filed April 9-, 1913.

Patented Apr. 14, 1914.

Serial No. 760,053.

The arm 1 is provided at one end with a plurality of openings 6 in which is adapted to be inserted a suitable hook member 7. Secured to the hook member is a coil spring 8, the lower end of which is adjustably mounted within the openings 9 formed in the standard 2 adjacent to the lower end thereof. An actuating rod 10 is provided, one end of which is secured to the arm 4 adjacent the pivot point and the other end thereof bent upon itself to form an eye 11, which is engaged over a transverse pin 12 mounted within the ends of the loop 13. The loop 13 comprises a suitable strip of sheet metal or other desirable material, the end portions of which are arranged in parallel relation and disposed upon opposite sides of the standard 2 to which they are pivotally secured by means of the bolt 14.

A transverse pin 15 is adj ustably mounted within the openings 16 formed in the parallel portions of the ends of the loop 13. Pivotally mounted upon the pin 15 is a foot lever 17 the outer end of which is bent at right angles to provide an engaging portion 18 adapted to be engaged by the foot to press the same downwardly upon the upper edge of the loop. The loop 13 is provided so that the foot treadle 18 may be arranged upon either side of the anvil and the lever 17 engaging the loop for actuating the arm 4. It will be readily apparent that the inner end of the lever 17 is to be loosely mounted upon the pivot pin 15 so that the lever may be moved in a horizontal plane to a certain extent. The punch, chisel or other tool is removably secured to the outer end of the arm 4 by means of the clamping blocks 19, one of which is removably secured to the outer end of the arm in any suitable manner and provided upon its inner face with a semicircular recess. The other of said blocks is provided upon its outer face with a metal plate 20, said plate having a rearwardly projecting lug 21 adapted to be hingedly mounted in the outwardly project ing plate 22. Pivotally secured to the other end of the plate is a rod 23 having a cam 24: pivotally secured to its other end, said cam engaging a curved recess formed in the outer end of the arm to securely clamp the two blocks to a punch, chisel or the like. A second one of the blocks 19 is provided with a semicircular recess adapted to cooperate with the recess in the first block to form a circular opening for the reception of the tool i said spring returning the arm to its norwhereby the same may be quickly and readily clamped to the outer end of the arm 4.

The device may be so arranged that the outer end of the arm 4 is disposed directly above the anvil, as illustrated at 22, said anvil being mounted upon a suitable support. It will be apparent that the operating lever 17 may be swung from side to side and disposed upon either side of the anvil support. In the practical operation of my device, the arm 4 is normally disposed in asubstantially vertical position, the tension of the coil spring 8 holding said arm in such position. The outer end of the arm 4 is pulled downwardly to a position just above the anvil, the upper-end of the rod 10 is then hooked within an opening 23 in the arm to hold the arm in its operative position. Any further downward movement of the arm will be brought about by downward pressureupon the lever 17 which will force the loop 13 downwardly pulling upon the rod 10 and arm 4. This operation will place the coil spring 8 under tension and the tension of l mal position after the same has been released. It will be apparent that the arm 4 may be quickly and readily longitudinally adjusted upon the standard by engaging any one of the notches 5 with the pin 3.

From the above description taken in con- 1 nection with the accompanying drawings, it i will be apparent that I have provided a simple and durable punch or chisel holder whereby the various tools may be securely '5 held in their operative position without the l use of the operators hands. It will also be apparent that the device is extremely simple i in construction and can be manufactured at a comparatively low. cost.

While I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope of the appended claim.

hat I claim is 2- A tool holder including a base, an upright standard mounted thereon, an arm adjustably mounted for pivotal movement upon the upper end of the standard, and normally disposed at an angle with respect to the standard, a coil spring having one end secured to the inner end of said arm and its other end secured to the standard to retain said arm in its normal position, a loop having its end portions arranged upon opposite sides of the standard and pivotally secured thereto, a rod having one of its ends removably engaged with the arm and its other end secured between the endportions of the loop,

an actuating lever having one end loosely secured to the ends of said loo-p and its other end extending beyond the intermediate porti on of the loop whereby downward pressure upon the outer end of said lever will actuate the arm.

In testimony whereof I hereunto affix my signature in the presence of two witnesses. PETER A. BURLOG.
